Ursodeoxycholic acid (UDCA) is a non-toxic, hydrophilic bile acid in widespread clinical use mainly for acute and chronic liver disease. Recently, treatment with UDCA in hepatic graft-versus-host disease has been given in immunosuppressive therapy for improvement of the biochemical markers of cholestasis. Moreover, it has been reported that UDCA possesses immunomodulatory effects by the suppression of cytokine production. In the present study, we hypothesized that UDCA may inhibit the production of the pro-inflammatory cytokine, IL-1$\beta$, and nitric oxide (NO) in microglia. In the study, we found that 100 $\mu$ g/mL UDCA effectively inhibited these two pro-inflammatory factors at 24 hand 48 h, compared to the $A\beta$42-pretreated groups. These results were compared with the LPS+UDCA group to confirm the UDCA effect. As microglia can be activated by several stimulants, such as $A\beta$42, in Alzheimers brain and can release those inflammatory factors, the ability to inhibit or at least decrease the production of IL-1$\beta$ and NO in Alzheimers disease (AD) is essential. Using RT-PCR, ELISA and the Griess Reagent System, we therefore found that UDCA in $A\beta$42 pre-treated cultures played a significant role in suppressing the expression or the production of IL-1$\beta$ and NO. Similarly, lipopolysaccharide (LPS) did not activate microglia in the presence of UDCA. Moreover, we found that UDCA exhibits a prolonged effect on microglial cells (up to 48 h), which suggests that UDCA may play an important role in chronic cell damage due to this long effect. These results further imply that UDCA could be an important cue in suppressing the microglial activation stimulated by massive AD peptides in the AD progressing brain.

Objectives: The object of this study was to identify the anti-inflammatory effects of Patrinia scabiosaefolia aqueous extract (PSE). Methods: RAW 264.7 cells were pre-treated with PSE and then incubated with or without lipopolysaccharide (LPS). Cell viability, production of nitric oxide (NO), secretion of pro-inflammatory cytokine, activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-${\kappa}B$) were measured. In addition, we observed mice survival rate after LPS and their cytokine levels of serum. We also observed inflammatory and hemorrhagic change on the histological sections of the liver. Results: PSE inhibited LPS-induced NO production, interleukin (IL)-6 secretion, c-Jun NH2-terminal kinase (JNK) and NF-${\kappa}B$ activation. In addition, PSE reduced the death rate of LPS-induced mice and IL-6 production on the serum of mice. PSE inhibited inflammation and hemorrhage on liver tissue as well. Conclusions: The results suggest that PSE have anti-inflammatory effects by inhibited NF-${\kappa}B$ and JNK activation, IL-6 secretion, and NO production. So PSE may be effective treatment for the inflammatory disease.

Raphanus sativus L. has been reported to have anti-inflammatory and anti-tumor activity. However, the anti-inflammatory effect and mechanism of action of the Raphanus sativus L. seeds (RSS) with or without oil are still unknown. This study was undertaken to investigate the in-vitro anti-inflammatory effect with or without oil in the RSS on RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Results showed the suppressed LPS-induced secretion of pro-inflammatory mediators such as nitric oxide (NO), inflammatory cytokine (IL-6, TNF-α). Additionally, a decrease in protein expression of iNOS was observed, but nuclear translocation of NF-κB p65 was not inhibited. To elucidate the underlying mechanism of the anti-inflammatory effect of RSS, the involvement of mitogen-activated protein kinase (MAPK) signaling pathways was examined. We also found that RSS blocked LPS-induced phosphorylation of c-Jun N-terminal kinase/stress-activated protein kinase (JNK) signaling but did not affect the phosphorylation of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2. These results suggest that RSS may have potential as an anti-inflammatory agent through the inhibition of LPS-induced inflammatory cytokine production via regulation of the JNK pathway.

Marine brown seaweeds are a source of functional ingredients with various biological properties. They have been used in the food and functional food industries. Brown seaweeds are divided into three parts of blades, stipe, and root. Normally seaweed blades were used as raw materials for biological research. However, there are limited uses on stipes of Ecklonia maxima (E. maxima) depending on the physicochemical, nutritional, and biological properties. Besides, the comparative studies of two structures of E. maxima, blades and stipe didn't discover previously. This study aimed to compare the potent antioxidant and anti-inflammatory activities of the two structures of E. maxima, blades and stipe in vitro studies to increase the utilization of the two structures of E. maxima. The enzyme-assisted hydrolysate from E. maxima showed significant antioxidant and anti-inflammatory activities. Among them, celluclast-assisted hydrolysate from E. maxima blades (EMBC) and viscozyme-assisted hydrolysate from E. maxima stipe (EMSV) expressed significant protection on hydrogen peroxide-induced oxidative stress. Moreover, EMBC and EMSV treatment remarkably reduced nitric oxide production by downregulation of pro-inflammatory cytokine expressions in lipopolysaccharide-stimulated Raw 264.7 cells. Especially EMBC showed strong inhibition on pro-inflammatory cytokine production compared to EMSV. Taken together research findings suggest that EMBC and EMSV possessed potent antioxidant and anti-inflammatory properties and may be utilized as functional ingredients in the food and functional food sectors.

Allergic contact dermatitis (ACD) is an inflammatory skin disease and regarded as a prototype of T-cell mediated delayed-type hypersensitivity reactions. Aroma Oil Complex (AOC) is composed of lavender true oil, chamomile roman oil and tea tree oil. This study was performed to assess the effects of AOC in a canine model of ACD. ACD was induced on the back of dogs induced by sensitization and repeated application by 2,4-dinitro-1-chlorobenzene (DNCB). Topical treatment of AOC was applied once a day for 8 days and skin biophysical parameters including transepidermal water loss (TEWL), skin hydration, skin thickness and erythema index, were measured every two days during experimental periods. Histopathology and immunohistochemistry were performed to evaluate the anti-inflammatory effect. In skin biophysical parameters, TEWL, skin hydration, skin thickness and erythema index were significantly increased, with a maximum increase appeared on day 2 (p<0.05). After the completion of AOC treatment, skin biophysical parameters were significantly reached those of baseline in a time-dependent manner (p<0.05). In histopathology, marked increases of epidermal thicknesses were induced after DNCB challenge with numerous inflammatory cell infiltrations and edematous changes, decreases of connective tissue occupied regions in dermis. In addition, marked increases of cytokine - tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$)-immunoreactivities in the dermis and of apoptotic markers - caspase-3 and PARP-immunoreactivities in the epidermis were observed in DNCB control as compared with intact control, respectively (p<0.01). The decrease of infiltrated inflammatory cells and related decreases of pro-inflammatory cytokine immunoreactivities were observed in AOC treated skin (p<0.01). Based on these findings, AOC may have anti-inflammatory and alleviatory effects in the allergic contact dermatitis.

This study was designed to examine the in vitro antioxidant and anti-inflammatory effects of red beet (Beta vulagaris) root. Red beet root was extracted using 70% ethanol and then fractionated sequentially with n-hexane, ethyl acetate and butanol. Antioxidative ability was evaluated by bioassays using total polyphenol contents and ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid diammonium salt) radical scavenging activity. Ethyl acetate fraction of red beet root was best on total polyphenol contents ($37.02{\pm}0.37mg\;GAE/g$) and ABTS radical scavenging effects ($IC_{50}$ $42.9{\pm}9.5{\mu}g/mL$). For the anti-inflammatory activity in RAW264.7 cells, the hexane fraction showed the highest inflammatory effect. Dose response studies were performed to determine the inhibitory effect of hexane fraction of red beet root on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The hexane fraction of red beet root inhibited the NO and $PGE_2$ production and the protein level of iNOS and COX-2, and protein expression of pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$), in a dose-dependent manner. These results suggest that red beet root has considerable potential as a functional food ingredient with antioxidative and anti-inflammatory effects.

Background : The importance of pro-inflammatory cytokines, especially tumor necrosis factor $\alpha$ (INF-$\alpha$) and interleukin-1$\beta$ (IL-1$\beta$), have been extensively documented in the generation of inflammatory lung disease. Lung epithelial cells are also actively involved in initiating and maintaining inflammation by producing pro-inflammatory mediators. Understanding the mechanism of pro-inflammatory cytokine expression in lung epithelial cells is crucial to the development of new therapeutic modalities for inflammatory lung disease. Transcription of most pro-inflammatory cytokines is dependent on the activation of NF-${\kappa}B$. However, the relationship between pro-inflammatory cytokine expression and NF-${\kappa}B/I{\kappa}B$ pathway in lung epithelial cells is not clear. Methods : BEAS-2B, A549, Na-H157, NCI-H719 cells were stimulated with IL-$1{\beta}$ or TNF-$\alpha$ at various times, and then IL-8 and TNF-$\alpha$mRNA expressions were assayed by Northern blot analysis. IL-$1{\beta}$ or TNF-$\alpha$-induced NF-${\kappa}B$ activation was assessed by the nuclear translocation of p65 NF-${\kappa}B$ subunit. The degradation of $I{\kappa}B{\alpha}$ and $I{\kappa}B{\beta}$ by IL-$1{\beta}$ or TNF-$\alpha$stimulation was assayed by Western blot analysis. The phosphorylation of $I{\kappa}B{\alpha}$ was evaluated by Western blot analysis after pre-treating cells with proteasome inhibitor followed by IL-$1{\beta}$ or TNF-$\alpha$ stimulation. The basal level of IKK $\alpha$ expression was evaluated by Western blot analysis. Results: $I{\kappa}B{\alpha}$ and $I{\kappa}B{\alpha}$ was rapidly degraded after 5 minutes of incubation with IL-$1{\beta}$ or TNF-$\alpha$ in BEAS-2B, A549, and NCI-H157 cells. The activation of NF-${\kappa}B{\alpha}$ and the induction of IL-8 and TNF-$\alpha$ mRNA expression were observed by IL-$1{\beta}$ or TNF-$\alpha$ stimulation in these cells. In contrast, neither the changes in NF-${\kappa}B/I{\kappa}B$ pathway nor IL-8 and TNF-$\alpha$mRNA expression was induced by IL-$1{\beta}$ or TNF-$\alpha$ stimulation in NCI-H719 cells. IL-$1{\beta}$ and TNF-$\alpha$-induced $I{\kappa}B$ phosphorylation was observed in BEAS-2B, A549, and NCI-H157 cells, but not in NCI-H719 cells. The basal level of IKK$\alpha$ expression was not different between cell. Conclusion : NF-${\kappa}B/I{\kappa}B$ pathway plays an important role in the expression of pro-inflammatory cytokine in most lung epithelial cells. The absence of the effect on NF-${\kappa}B/I{\kappa}B$ pathway in NCI-H719 cells sæms to be due to the defect in the intracellular signal transduction pathway upstream to IKK.

Dysregulation of inflammation induced by noninfectious stress conditions, such as nutrient deprivation, causes tissue damage and intestinal permeability, resulting in the development of inflammatory bowel diseases. We studied the effect of autophagy on cytokine secretion related to intestinal permeability under nutrient deprivation. Autophagy removes NLRP3 inflammasomes via ubiquitin-mediated degradation under starvation. When autophagy was inhibited, starvation-induced NLRP3 inflammasomes and their product, IL-1β, were significantly enhanced. A prolonged nutrient deprivation resulted in an increased epithelial mesenchymal transition (EMT), leading to intestinal permeability. Under nutrient deprivation, IL-17E/25, which is secreted by IL-1β, demolished the intestinal epithelial barrier. Our results suggest that an upregulation of autophagy maintains the intestinal barrier by suppressing the activation of NLRP3 inflammasomes and the release of their products, including pro-inflammatory cytokines IL-1β and IL-17E/25, under nutrient deprivation.
